Abstract (en)

[origin: WO9858016A1] A polymer composition having naphthalenedicarboxylic residue includes a fluorescence quenching benzylidene compound capable of absorbing ultraviolet light radiation. In a preferred embodiment, the composition includes at least a 0.1 mole percent of naphthalene-2,6-dicarboxylate and about 0.01 mole percent to about 5 mole percent of a benzylidene compound having structure (I), wherein R is selected from the group consisting of hydrogen, C1-C8 alkyl, substituted C1-C8 alkyl, C3-C8 alkenyl, C3-C8 alkynyl, C3-C8 cycloalkyl, C3-C8 cycloalkenyl and -R2-X, wherein R2 is selected from the group consisting of C1-C8 alkylene, C2-C8 alkylene-O-C2-C8 alkylene, C2-C8 alkylene-S-C1-C8 alkylene, C2-C8 alkylene, C2-C8 alkylene-S-C2-C8 alkylene, C2-C8 alkylene-N(SO2 C1-C8 alkyl)-C2-C8 alkylene and X is selected from the group consisting of hydroxy, carboxy, carboalkoxy and acyloxy; R1 is hydrogen or has 1-3 groups independently selected from the group consisting of hydroxy, C1-C8 alkyl, C1-C8 alkoxy and halogen; Y is selected from the group consisting of carbalkoxy, cyano, carbamoyl, substituted carbamoyl, aryl, aroyl, C1-C8 alkylsulfonyl and arylsulfonyl.
